LUBRIOATING-CUP FOR STEAM-CHESTS AND THE LIKE.

To all wlwnm't may concern:

Be it known that I, 'luomas (Jamaica, citizcn of the United State-s, residin; at the city and county of San l ranelsoo and Statoot (Jahfornia, havo invented new and u.-;e'l'ul lin- Specificntion 01 Letters Patent.

hosts and tho liilie, of which the following i is a specification.

'lhm invontion relates to lubricating devioos, and )ortaiua especially to lllmlllr l'or automationll rogulatiny; ho l'ood ol graph-- ito or other lubricant to a cylinder, steam oho. t, or thelike.

'lbefinvontion consists o'l tho parts and the construction and combination ol parts as horoinnllornioro fully (lmoribod and olaina'd, huvin referelioe to the aei'o npanying d rawings, in Whieh Figure 1 is a central seot ion of tho devioo. Fig. 2 is an elevation of the valve. Fig. 3 is a bottom plan ol' name. Fig. 4 shows the doviee :H apiliod to n hlC- llll ehesl. Fig. 5 shown a. inoil iiioation.

A re-prcsonts a cup or other suitable recep tacle for holding graphite or the like. This rap is sot-owed into or otherwise at tachcd to a stoma chest or cylinder, the interior of which it is doairod to lubricat-o. 'l'ho top of tho oup may he closed by any suitablo means, and tho bolt-om ol tho cup has an outlet opening into the intorior ol the steam cliost or cylirahir, with a double-milled sectional valve 2'; adaptod to soot in the bottom opcnin of the cup. ing, and tho two aoctio'ns of the Volvo are held tog-other by a bolt 4 passing centrally through the sections, and the. set nuts 5- scrcwlng on to the bolt. The bodies of tho valve sections arc rocoasod 0r grooved lonitudinally, as rcprcsontod at 6,-to provido ubricating ducts for thodischarge of the lubricant periodically from tho cup into tho cylinder. Those groovos or ducts in the. two

sections a-ro adapted to be brought int-o rogistor, or cam'iod to onc side, or the othor, more or lossout of rogiotor, by turning one valv ooction relative to the other, for tho )urpos'o of rostrictin' or ol'ilargiiig thoso lubricating ducts, and thorob' control the food of the lubricant to the cylinder. Ear-h valve section ad'acont to its seating oud may bo provided 'wit I an annular groove 7 con- This valvc'b' is double-scat.

The abutting cnds of the sections are provided n'ith suit able. inlorlockin moans by which tho size. of the ducts may lie nnlintainod uniform after )roper regulation. lie-re shown, consists of a dowel-oi 8 in the inner end of one section re istera )lowith one or other ol' the holon J in the abutting; cncl of the oppoxito section.

in practice, the pressure in the cylinder or steam cheat, wlu-thor from steam, air, gas or other tluid, exerted against the under sidoof the valve. lifts the valve to close it against its lower sent 10, thereby allowing the lubricant, such on graphite, to drop into the grooves of the valve. As soon as tho re.-. suro in the cylinder or chest in rolrasm so that the valve may drop by gravity, the latter olosoa over its up ier seat 11, thoroby prevonting any more lu rieant. entering the grooves, but allowing t hoe-ha] gool' lubricant in lhogroovos to drop into the \lin 'lel or chest.

11'] order to provenl the splashing of the raphite when tho ralvo opons downward to ot tho ehurgo of graphite drop out of the grooves, and to enablo, also, a suitable lubriouting oil to bemixed with tho graphite before it onto-rs the steam chest or cylinder, l may employ asup )leniental plug, as 12, into the top of which t to cup A may screw; this plug in turn serewing into the steam chest or cylinder.

oha-n'c outlet. 14. Enterini; eha-mbor 13 is a shitaole oil pipe 15 throng i which oil is admitted in suit-aisle quantities and-at suitable intorvala. In this case the ohm-"o of graphite is deposited first in (EllitlllJGl l3 and therein mixed withoil, so that tho commingled oil and graphito foods downward into i the va ve drops and dcposits lts charge of graphite into the chest, whence it works lions, each section having a seating portion,

around the valve and thence into the eylinder. The size of the ducts 6 is re nlated so as to deliver a suitable snpdlyoi graphite wh never the valve is allowed to drop. As a matterpffiiapt, the action of the valve 2) is not continuous, and need not be, since the oceasional starting and stopping ol the engine provides for a sullieient quantity of graphite to pass into the steam chest and cylinder.

hor stationary engines, or elsewhere where it is desired to quantity of grap ite and oil, the'cup A with periodically feed a delinite l its pressure-operated valve may screw into a valve casing 17 which has a plug valve 18 by which the pressure from the chest 19 may be controlled so as to allow the valve 3 to open or close. The top of the casing 17 has a petcoek 20. Ordinarily with plug 18 turned so that the pressure from the steam chest may act on the under side of the valve 3, the petcock 20 is closed. With the valve 3 thus lifted, the grooves are allowed to fill; the sections of the valve bein turned so as to make the grooves the desired size to contain the desire guantity of raphite which is to be delivere periodical y. When the plug 18 is turned to shut off communication with the chest, the pet-cock 20 is opened to relieve the pressure in the casing 17, thereupon allowing the body of the sections having longitudinal n gi temble grooves, connecting means passin; through the slt lluiis and permitting the :(t'lifllls to have a lnrnablo mover rent to widen or narrow snid groin-es, and interlocking means on the abutting ends of the sections.
